WATERrCLOSET.

Specification of Letters Patent.

Application filed June 30, 1910. Serial No. 569,802.

To all whom it may concern: Be it known that I, IRA A. MANN, a pitizenof the United States, residing at PltllS I burgh, in thecounty ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Water-Closets, of which the following is aspecification.

The invention relates to water closets and particularly to what areknown as wall closets, that is closets hung or supported from the wallas opposed to those in which the support is from the floor. Theinvention has for its primary objects, the provision of a Wall closet inwhich the distance the bowl projects from the wall is reduced to aminimum; the provision of a wall closet in which the siphon is entirelyinclosed in the bowl structure in a novel and compact manner permittingthe center line of the bowl to be placed close to the wall upon which itis supported; and the provision of improved means for rigidly supportingthe bowl without injury I to the wall or to the bowl. Certainembodiments of the invention are illustrated in the accompanyingdrawings wherein Figure 1 is a side elevation, partially in section, ofthe improved closet as applied a wall.

Figure 2 is a partial plan view and section taken just above the closet.

Figure 3 is a rear view of the closet removed from the wall.

Figures 4 and 5 are a plan view and side elevation, of the bowl removedfrom the wall the elevation in Fig. 5 being taken from the opposite sidefrom that shown in Fig. 1.

' Figure 6 is a plan view of the bearing plate employed behind the wallor partition.

Figures 7' and 8" show a modified bowl structure.

Fig. 9 shows still another form of bowl structure.

Figures 7, 8 and 9 are enlarged detailed views showing the im rovedjoint construction. Figure 7 being a section through the joint member inthe bowl; Figure 8 being an end view of the joint member of Fig. 7 andigure 9 being a side view of the coupling member for engaging the jointmember shown in Fig. 7.

Figures 10 and 11 are sectional and end view respectively of the toolemployed for positioning the coupling shown in Fig. 9.

Figures 12 and 13 are enlarged detailed view of a modified form of jointmember and coupling which may be employed, F igure 12 being a sectionithrough the joint member and Fig. 13 being a side view of the couplingmember employed therewith,

and

Figures 14 and 15 are sectional and end views respectively of the toolto be employed in positioning the coupling of the Fig. 13.

Referring to the general arrangement as shown in Figures 1 and 2 theprincipal parts may be enumerated as follows. 1 is the bowl of thecloset having at its rear side the plate or shelf 2 bearing against thesupporting wall or partition 3; 4 is a metal bearing plate placed behindthe wall or partition 3 and secured to the shelf 2 by means of the bolts5; 6 is the outlet or soil pipe provided with the vent pipe 7 to whichthe bearing plate 4. is secured by means of the loop 8; 9 is a metaljoint member secured in the bowl; 10 is a coupling for connecting thejoint member 9 to the soil pipe 6; 11 and 12 are the seat and coverrespectively. which members are pivoted to the fixtures 13 and 14carried by the bolts 55 in the manner indicated in Figs. 1 and 2-; and15 and 16 are cross members carried by the framing of the partitionalwall to which cross members the metal bearing plate 4 is secured.

One of the important features of my invention consists in thearrangement of the siphon passage whereby the space in the bowl to therear thereof occupied by the passage is reduced and the bowl placednearer to the wall than would be the case if the siphon passage wereotherwise arranged. The siphon passage is indicated in dotted lines inFigs. 1, 3, 4 and 5, and by reference? to these figures it will be notedthat thefoutlet 17 from the bowl to the siphon passage extends laterallyinstead of to the rear as in the ordinary form of bowl construction.From the outlet 17 the passage extends upwardly and rearwardly asindicated at 18 in Fig. 1, thence curves laterally as indicated at 19,thence curves downwardly as indicated at 20 and finally curves to therear as indicated at 21. It

will be seen that by this arrangement it is necessary to provide spacebetween the bowl orifice and the wall for one diameter of the siphonpassage only, whereas if the ordinary siphon arrangement were employedextending straight back from. the outlet instead of sidewise, it wouldbe necessary to provide space for two diameters of the siphon passage,ind the bend at the upper end of the siphon would either occupyconsiderable space, or would have to be bent so short as to reduce theflow of the Water therethrough. By the arrangement shown contractedbends are entirely avoided, thus insuring a free flow of water throughthe passage, and the lateral enlargements in the bowl structure incidentto the use of the side outlet are so slight and in such position thatthe appearance of the bowl is not seriously affected. The siphon jetpassage-is indicated at 22, such siphon jet passage having its outlet at23.

The provision of the bearing plate 4 is important as such plate servesto give a very firm support for the bowl, which support would notordinarily be afforded by the ordinary wall or partition. The bolts 5serve to support the plate or shelf 2 and at the same time form thesecuring means for the seat fixtures or brackets 13 and 14. The bearingplate is forked to surround the outlet pipe 10 as indicated in Fig; 6,and its extreme ends are turned back as indicated at 24 and 25 (Figs. 1and 6) in order that the plate may be more securely supported upon thetransverse beams 15 and 16, which beams are ordinarily supported on theusual timber uprights 26. A number of holes 27 are provlded through theplate 4 to receive screws or other securing means, the plate beingpreferably secured to the beams 15 and 16- y means of screws. A veryrigid support for the bearing plate is thus provided. and this supportis still further increased by means of the strap or loop 8 passingaround the vent pipe 7 and secured to the plate 4 at its ends. Asindicated in Fig. 3 the holes 28 in the shelf 2 for receiving the bolts5 are somewhat'elongated in order to permit of a vertical adjustment ofthe bowl and to permil; the bowl to move vertically a slight amount toadjust itself to the expansion of the soil pipe 6 to which the bowl isrigidly secured. The invention, in so far as the means for supportingthe bowl from the piping are concerned, is applicable to other types ofbowls used in plumbing aside from closet bowls.

The joint construction which is preferably used is shown in detail inFigs. 7, 8 and 9. A joint member 9 having inclined recesses 30 and atapered ground surface 31 is secured in the bowl by means of the lead orother packing 32, and this member is adapted to be engaged by thecoupling memco6perating with the surface 31.

ber 10, whichmember 10 is provided with lugs 32 for cooperating with therecesses 30 and with the ground tapered surface 33 for The other end ofthe member 10 is provided with the usual tapered pipe thread 34 forengaging the thread upon the interior of the pipe 6. The tool employedfor screwing the coupling 10 into the pipe 6 is shown in Figs. 10 and11. This tool is provided with a wrench engaging portion 35 and has uponits inner surface a tapered portion 36 and inclined lug engagingrecesses 37, which surface and recesses are exact duplicates of thoseupon the joint member 9. This member will therefore screw upon the outerend of the member 10 and the portion '34 can then be screwed into thepipe 6 until it is tight. If, when screwed in tlght, the lugs 32 do notoccupy their proper rotative positions or if they are too far out fromthe wall, the member 10 is removed and a member of slightly differentlength is substituted or else the screw thread upon the interior of thepipe is cut a trifle farther, and this member is then screwed into thepipe 6. This method of adjustment is pursued until the lugs 32 upon theend of the member 1 0 occupy exactly the proper position rotatively andlongitudinally when the other end of the coupling is screwed tightlyinto the pipe 6. The accuracy of the position of the outer end of thmember 10 can be readily gaged from the tool employed in screwing thecoupling into position, as the flange 38 is' so positioned that it willengage the wall when the coupling is properly positioned, and thisflange is also provlded with a mark 39 (Fig. 11) which serves toindicate the proper rotative position of the lugs 32. After the coupling10 is thus properly positioned the bowl 1 is placed so that the jointmember 9 fits over the outer end of the coupling 10 and is given amovement to upright position, which movement causes the lugs 32 toengage the recesses 30 and draw the tapered surface 33 tightly againstthe surface 31.

In Figs. 12 and 13 a modified form of joint member 9 and coupling member10 are shown, such connecting means difiering from that shown in Figs.7, 8 and 9 in that an ordinary thread is provided between the interiorof the joint member and the coupling member instead of the quick threadconnection. This form of connection, of course, requires that the bowlbe rotated a number of times in order to screw it to position, and theconnection cannot therefore be used in those cases in which the outletis as close to the floor as that shown in Fig. 1, as the bowl cannot inthis construction make a full revolution. This form of connection can bevery cheaply made, and the coupling member 10' is adjusted by means of atool 39' which screws onto the end of the conpling member, the method ofadjustment being substantially the same as that heretofore describedwith relation to the device shown in Figs. 7. 8 and 9.

In i l 7 and S a modified form of bowl structure is shown, thearrangement of the siphon passage being somewhat different from thatshown in Figs. 1 to In this arrangement the short leg 40 lies moredirectly at the side of the bowl and is provided at its upper end withthe recurved portion 41 for improving the draw. point the passage curveslaterally to the center of the bowl as indicated at 42 and then to therear as indicated at 43.

In Fig. 9 still another form of bowl is shown in front elevation, bothlegs of the siphon 44 and 45 lying to the front of the bowl orifice withthe substantially horizontal portion 46 extending backwardly under theorifice of the bowl to the outlet in the rear side of the bowlstructure.
